The EPA may also choose to provide an exemption to the requirement of an established tolerance level, allowing any amount of a pesticide residue to remain on or in food or feed ...

Pesticides can enter the body through inhalation of aerosols, dust and vapor that contain pesticides; through oral exposure by consuming food/water; and through skin exposure by direct contact. [96] Pesticides secrete into soils and groundwater which can end up in drinking water, and pesticide spray can drift and pollute the air.
Because the processes producing these wastes can occur in different sectors of industry, the F-listed wastes are known as wastes from non-specific sources. (See 40 CFR 261.31) The K-list (source-specific wastes). This list includes certain wastes from specific industries, such as petroleum refining or pesticide manufacturing.
The Food Defect Action Levels: Levels of Natural or Unavoidable Defects in Foods That Present No Health Hazards for Humans is a publication of the United States Food and Drug Administration's Center for Food Safety and Applied Nutrition [1] detailing acceptable levels of food contamination from sources such as maggots, thrips, insect fragments, "foreign matter", mold, rodent hairs, and insect ...
Leaching is affected by the soil, the pesticide, and rainfall and irrigation. Leaching is most likely to happen if using a water-soluble pesticide, when the soil tends to be sandy in texture; if excessive watering occurs just after pesticide application; if the adsorption ability of the pesticide to the soil is low.
